They started with Captain America: Winter Soldier then moved onto Captain America: Civil War and now the Russo Brothers are directing both installments of Avengers: Infinity War. One of their favorite games has been to post close-up pictures of props on set to their Twitter. The pictures always act as a tease to the audience due to the props not being immediately recognizable. During the Civil War the Russo Brothers posted a close-up picture of Spider-Man mask — at least we think that’s what it was. During infinity war filming, the first picture they posted was of an explosion — at least we think it was an explosion.
And now, today, the Russo Brothers have struck again with a picture that is not immediately decipherable.

So what is that?
We have a theory.
We know production has move to Africa, presumably for scenes in Wakanda. The object appears to be an airlock of some sort. It also appears to be made into the floor, with a pale blue, icy light. So the question becomes what important thing is in Wakanda that needs to be behind an airlock?
Bucky, the Winter Soldier.
At the end of Captain America: Civil War, we saw the Winter Soldier put into cryogenic deep-freeze in Wakanda, left under the care of T’Challa, the Black Panther, until such a time as they can figure out how to reverse the brainwashing done to him by the Russians. With the cosmic level threat of Thanos on his way to earth, Captain America and Black Panther and the rest of the avengers are going to need all the help they can get. Whether he is ready or not, the Winter soldier is being a weekend for one more mission — save the world.
Or it’s the entrance to a Wakanda sewer system — what do we know.
He has two cats and knows all things about Doctor Strange but little else.
